NCS32100 and NCV77320

NCS32100 offers a full featured controller and sensor interface for high resolution high accuracy angular sensing when paired with a printed circuit board sensor.  The NCS32100 has flexible configuration capabilities allowing for connection to a variety of inductive sensor patterns and offers a variety of digital output formats.  Inductive sensing techniques have unique advantages over traditional position sensor solutions including but not limited to temperature insensitivity, mechanical simplification, and insensitivity to contaminants.The NCV77320 is an inductive position sensor interface that, in combination with a PCB, forms a system to measure angular or linear positions accurately. The operating principle of the inductive sensor is based on mutual inductance. The chip contains an excitation source, which generates an AC magnetic field through a primary coil on the PCB. The field mutually couples to the rotor. The rotor on its turn induces voltages in secondary coils. These voltages, measured by the chip, depend on the rotor position and give a measure for the position. The NCV77320 contains 3 interfaces: A single ended analog output, a SENT interface with fast and slow channel and a SPI channel for direct interconnection to a micro controller. The analog output is proportionally ratio metric with the supply voltage. The NCV77320 has several fault detection circuitries. When a fault is detected, fault flags are set and available for readout.
